(a)
Interpretation:
The given starting compounds and selective reagents used to accomplish the target products transformation should be draw and identified.
Concept introduction:
Wittig reaction: This process allows the preparation of an
Markovnikov addition: The addition reaction of parotic acids to a different alkene or
Grignard Reaction: This is a organometallic reaction in different alkyl, aryl-magnesium halides add to a carbonyl group in an aldehyde and ketone. This reaction is an important for the conversion of carbon-carbon single (-C-C-) bond. Moreover the addition of a reagent to an aster, lactone gives a tertiary alcohol in which wo alkyl groups are the same and the addition of a Grignard reagent to a nitrile produces an unsymmetrical ketone.
NaBH4 Reduction: The saturated/unsaturated aldehyde and
Acid Catalyzed Hydration Reaction: The reaction involves breaking of π-bonds between carbon-carbon multiple bonds and addition of alcohol to more substituted position of carbon in the molecule.
Addition Reaction: It is defined as
To identify: The reagents used to accomplish the given transformation.
(b)
Interpretation:
The given starting compounds and selective reagents used to accomplish the target products transformation should be draw and identified.
Concept introduction:
Wittig reaction: This process allows the preparation of an alkene by the reaction of an aldehyde (
Markovnikov addition: The addition reaction of parotic acids to a different alkene or alkyne, the hydrogen atom of
Grignard Reaction: This is a organometallic reaction in different alkyl, aryl-magnesium halides add to a carbonyl group in an aldehyde and ketone. This reaction is an important for the conversion of carbon-carbon single (-C-C-) bond. Moreover the addition of a reagent to an aster, lactone gives a tertiary alcohol in which wo alkyl groups are the same and the addition of a Grignard reagent to a nitrile produces an unsymmetrical ketone.
NaBH4 Reduction: The saturated/unsaturated aldehyde and ketones in the presence of sodium metal in NaBH4 and carbonyl compound produced saturated alcohols. The keto group involves in the reduction process of NaBH4, this end up reducing to give the alcohols.
Acid Catalyzed Hydration Reaction: The reaction involves breaking of π-bonds between carbon-carbon multiple bonds and addition of alcohol to more substituted position of carbon in the molecule.
Addition Reaction: It is defined as chemical reaction in which two given molecules combines and forms product. The types of addition reactions are electrophilic addition, nucleophilic addition, free radical additions and cycloadditions. Generally, compounds with carbon-hetero atom bonds favors addition reaction.
To identify: The reagents used to accomplish the given transformation.
